章 (zhāng): measure word for chapters

The new Chinese teacher in our class is surnamed Zhang, and everyone calls him Mr. Zhang.

Zhang Ming was my college roommate; after graduation we rented an apartment together in Shanghai.

The person listed first on the name list is Zhang Xiaohong; she is the organizer of this event.

Mom asked me to call Auntie Zhang to thank her for the fruit she brought over yesterday.

I ran into a Mr. Zhang at the subway station; he happened to be heading to the same place, so we walked there together.
